A reasonable concern. I would then recommend you post a HiJackThis log. Mention your banking concern there, mention what we have run here. Of course the Truest form of action would be a full format and reinstall to completly guarantee everything. But you can still do that after the HJT Team looks.
Please follow the instructions in this tutorial for posting a HijackThis Log. Preparation Guide for use before posting a HijackThis Log
After you have created it,post the log here HijackThis Logs and Malware Removal
in this topic,thanks.
Click on New Topic and copy/paste the entire log
into the reply. Give it a relevant title. Perhaps "Need to be certain for banking"
Once you have posted the log DO NOT reply to it or change it until contacted or advised to do so by the HJT Team
Should you have any other questions about this ask those here.
